PITTSFIELD — With investment income now covering one-third of its budget, the Berkshire Museum is back in supporters’ mailboxes with an upbeat report — and a different kind of “ask.”

The appeal will test public willingness to donate to a nonprofit whose leaders in 2017 opted to close operating deficits by cashing out much of its most valuable works of art.

In his first Annual Fund appeal since joining the museum as executive director last spring, Jeff Rodgers skips what he terms the typical money pitch. It is the first such campaign since the museum raised $53.25 million by selling 22 pieces from its collection.
